This has worked for me on a MacOS Catalina with HomeBrew 2.2.5: pip install pygraphviz --install-option="--include-path=/usr/local/Cellar/graphviz/2.42.2/include" --install-option="--library-path=/usr/local/Cellar/graphviz/2.42.2/lib" |

Hi, I have MacOs BigSur on MacBook Air ARM M1, I have the same issue with pzgraphviz 2.44.1 Here's the log:

It seems you are using anaconda, can you try If not, have you tried adjusting the paths to your brew installation? $ pip install --install-option="--include-path=$(brew --prefix graphviz)/include" --install-option="--library-path=$(brew --prefix graphviz)/lib" pygraphvizAlternatively, please double-check your paths and report back to us – your log mentions |
Hi, thank you for your help. I tried with Honda but it seems it doesn't allow me to install with because of my python version (Do you confirm pygraphviz doesn't support python 3.8?): Using instead the adjusted paths of brew with pip seemed work: but than it raises me error when I try to import the library in python; It is pheraps connected to my incompatible version of Python? |

There is a release candidate (1.7rc1) out now that tries to address some of these issues. If you are on a mac and have installed Graphviz with homebrew, then installation of pygraphviz should work out-of-the-box. You can try the pre-release with pip: The install instructions for macOS have also been updated to provide recipes that should work for users who have installed Graphviz via macports as well. |
|
Pygraphviz 1.7 has been released which includes and updated installation procedures for installing on all platforms including Windows and macOS. Please see the updated installation guide for details on your specific platform. If you are still having problems or your use-case is not covered in the documentation, please open a new issue with info about your platform and how Graphviz was installed. |

Ubuntu 20 here. This worked for me
|
Thank you guy, it worked for me too, Ubuntu 20.04. |

On mac osx M1 I just did
|
|
This worked for me (Mac OS ver 12.3.1, homebrew 3.4.7, homebrew graphviz 3.0.0) |
|
this was the final straw: |
Thx your command work for me as well |
|
On Ubuntu, use this: sudo apt-get install python3-pygraphviz |
|
I'm getting this same error, but on SUSE. None of the solutions above has worked for me (so far). I installed graphviz with zypper, but still get the same error. |

Is there a solution that uses just |
Unfortunately, no. |

I was running into pretty much the same issue on RHEL with Python 3.8 few days ago, getting: running build_ext ERROR: Failed building wheel for pygraphviz turns out that line 49 in /usr/include/graphviz/types.h was something like: #include <cgraph.h> |

Apple M1 user here. I believe the solution is to provide the correct path for the pip to find the header file. brew install graphviz will install graphviz onto the computer. but when installing graphviz for python first pip needs to know the location of the graphviz that has previously installed. in my case the homebrew chose to install graphviz in this directory: /opt/homebrew/Cellar/graphviz/8.0.1/ so with additional flag specifying the header files and lib it should be fine: pip install --install-option="--include-path=/opt/homebrew/Cellar/graphviz/8.0.1/include/" --install-option="--library-path=/opt/homebrew/Cellar/graphviz/8.0.1/lib" pygraphviz the path might vary from person to person. just make sure you can find the file and it should work. |

MacOS Apple Silicon 13.4.1 (22F82) this solved it for me then: |

@zikkuratti could you please open a new issue with the exact versions of pygraphviz, graphviz, operating system and how you installed graphviz and pygraphviz? Thanks! |

Had the same problem on Linux aarch64 (ARM). Solved it like this with inspiration from the reply above: sudo apt install libgraphviz-dev
export C_INCLUDE_PATH="/usr/include/graphviz:$C_INCLUDE_PATH"
export LIBRARY_PATH="/usr/lib/aarch64-linux-gnu/graphviz:$LIBRARY_PATH"
pip install --use-pep517 pygraphvizI tried this format: pip install --use-pep517 \
--config-setting="--global-option=build_ext" \
--config-setting="--build-option=-I/usr/include/graphviz" \
--config-setting="--build-option=-L/usr/lib/aarch64-linux-gnu/graphviz" \
